Intermediate commit while converting to the new architecture
  * Converted Filtration into StaticPersistence and DynamicPersistenceTrails
    (both right now work with the underlying std::vector rather than std::list order)
  * Filtration is now just an auxilliary glue (a map between Complex and Persistence)
  * Whether chains are vectors or lists can be interchanged
  * Added PersistenceDiagram with a simple bottleneck_distance() function
  * Converted triangle, alphashapes3d, and cech-complex examples
  * Lots of organizational changes
    (factoring utilities out into containers.h, indirect.h, property-maps.h)
  * Trying to document along the way with NaturalDocs-type comments
